Abstract: 279,555. Caufield, N. H. July 29, 1926. Shocking-machines.-A shocking-machine comprises a tiltable basket formed with pivoted side plates and independent displaceable end and bottom plates into which the sheaves are deposited by :an elevator, means being provided whereby on the operation of a control member the elevation is thrown out of action and the basket tilted to deposit the shock, the elevator being thrown into action again automatically when the basket resumes its normal position. The side plates of the basket pivot about a horizontal axis and move inwardly, the bottom plate being mounted on links whereby it is inverted. The end plate moves from a vertical to a slanting position, while above is a pivoted presser plate forming the top of the basket. All these members are operated from a crank shaft actuated, through a manually -operated clutch, from the ground wheel of the machine. The machine comprises a frame 10, Figs. 3 and 4, mounted on wheels 13 - - 15, the wheel 13, serving as a driving-wheel, being connected by chain gearing 17 to a sprocket 18, and by bevel gearing 32 to a lay shaft 34 which drives, by means of a clutch connection, a second sprocket 36 through which the. elevator is driven. The sprocket 18 is fitted with a clutch for driving a shaft 19 from which the basket-operating mechanism is driven. As shown in Fig. 10, the sprocket 36 carries an eccentrically-pivoted, spring-influenced member 60 having a boss 61 which engages projections 63 on a clutch member 64 fixed to the shaft 34. The member 60 has projecting ends 62 which may be engaged to move the boss 61 out of engagement with the rollers and disconnect the drive to the sprocket 36, by the depression of a lug 64<1> on a pivoted cross member 65. This is effected through a link 67 and a dog 69 operated by a cam 70 on the shaft 19. The shaft 19 carries a pivoted pawl 23 which is operated to engage a slotted clutch member 21 on the sprocket 18 by a pivoted arm 25 normally held in the position shown by a manually-operated spring pin 27. On the release of the pin the pawl 23 engages one of the slots and the shaft 19 is rotated to operate the basket, tilting mechanism. At the same time the cam 70 releases the dog 69 and the lug 64<1> engages the pivoted member 61 to stop the drive to the elevator. On a complete rotation of the shaft 19 the arm 25 re-engages the pin 27 to withdraw the pawl 23, and the cam 70 effects the lifting of the dog 64<1> to re-start the drive to the elevator. The elevator comprises endless chains carrying cross members 50, Fig. 7, fitted with tines 51 which are projected on their upward path by the engagement of cranked members 54 with stationary guides 55. The basket is operated by the shaft 19 which is provided with a cam 73 and crank arm 74 connected by a, cross shaft 79 to a similar crank arm 78 and cam 77 on a stub shaft 76 at the other side of the machine. The side plates 82. 83 of the basket are each pivoted on a stub axle 89 having a bell-crank 91 connected by a link 92 with crank arms, 81 on the shaft 79. The side plates are caused to move inwardly on being tilted by the provision of arms 111 operated by cams on the shaft 19 and stub shaft and provided with cam slots 113 engaging the ends of arms 114 connected with the vertical ribs on the side plates. Pivotally connected with the ribs 86 is a frame 95 which supports the top or compressor plate 96 operated by arms 97 mounted on the shaft 79. Also supported on the ribs 86 is a rear plate 100 having a lower hinged section. This plate moves from a normally vertical position to a slanting position and is furnished with side rollers riding on fixed guides. The lower part of the basket consists of a plate 104 which moves from a normally horizontal position to a vertical position and is then inverted. For this purpose it is connected by arms 106, 107 connected respectively to the plate 88 and ribs 86.
